PURPOSE:To obtain a rotary seat accessible to the side wall by inserting a sliding pin loosely into front and rear grooves of a seat base as provided eccentrically at the lower end of a rotary shaft inserted through a sliding frame on the seat base. CONSTITUTION:A turning seat frame 4 is provided in such a manner as to turn with a rotary shaft 3 inserted through a sliding frame 2 moving horizontally on a seat base 1. Then, the sliding pin 5 provided eccentrically at the lower end of the rotary shaft 3 is inserted loosely into front and rear grooves 9 longitudinally cut into the seat base 1. The seat base thus arranged turns pivoting around the sliding pin 5. With further turning of the seat base, the sliding pin 5 moves through the front and rear groove 9 as the rotary seat frame 4 turns to thrust the sliding frame 2 away from a side wall 17 to the seat base while the sliding pin 5 moves within the front and rear groove 9. This prevents a turning seat pad 15 from contacting the side wall 17 thereby obtaining a seat accessible to the side wall 17. |
